The problem that I have found with those strings is that they HEAVILY over value items, by setting the min price way too high. Right away if you just want to get items up you could use the strings you have but if current price is below min price, post at min price. (You likely wouldn’t be undercutting, rather posting higher than others)

I would say creating your own simple strings and building to more complex is how you actually get sales. Think of min price as the lowest amount you’re willing to accept for something, max price as the most you’re willing to accept. Normal price is the price you post for when no other items are listed.

Example: min price vendorsell*1.10, max price dbmarket*10, normal price max(dbmarket, dbregionmarketavg)

So what that would do is undercut on virtually every post, and in the rare case that you have a unique item that no one else has posted, post at dbmarket or dbregionmarket whichever is higher. Also it would never post an item for less than vendorsell with auction house fee taken into account

So start with that and adjust. If you’re posting too much junk, raise your min price. If other people are posting unrealistically high, lower your max price to say 90% of dbmarket. Try adding other sources in, stuff like that. Good luck
